DFC Brake Rotor - Drilled and Slotted - Black Product Line

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots to enhance brake pad bite and improve water and gas evacuation. The zinc black hat finish provides corrosion resistance, extending rotor life in various driving conditions. This product line is designed for solid rotors with directional surfaces to optimize braking efficiency and heat management.

Detailed Product Description

This Dynamite Friction disc brake rotor is a solid, directional rotor featuring a drilled and slotted surface type. The drilled holes help dissipate heat and gases generated during braking, while the slots assist in cleaning the brake pad surface for consistent contact. The rotor’s plain disc finish and zinc black hat finish with rust-resistant coating provide durability against corrosion. With a nominal thickness of 12.5 mm and a discard thickness of 10.5 mm, this rotor maintains structural integrity throughout its service life. The 4-bolt hole pattern with a 103 mm bolt circle diameter and 81 mm center hole diameter ensures compatibility with specific vehicle applications requiring these dimensions.

Common Applications and Issues Addressed

• Reduces brake fade during heavy braking or towing
• Improves braking performance in wet conditions by evacuating water
• Minimizes brake pad glazing and uneven wear
• Helps maintain consistent pedal feel under demanding driving
• Prevents rust and corrosion on rotor hats for longer service life

Installation Notes and Tips

Ensure the rotor is compatible with your vehicle’s bolt pattern and hub dimensions before installation. Clean the rotor surface to remove any protective coatings or residues prior to mounting. Use proper torque specifications on lug nuts to avoid warping. Directional rotors must be installed with the correct rotation direction for optimal performance. Check rotor thickness regularly and replace when below the discard thickness of 10.5 mm.

Quality Assurance

Dynamite Friction manufactures this rotor to meet industry standards for durability and performance. The rust-resistant zinc black coating on the hat extends corrosion resistance. While no specific warranty information is provided, adherence to recommended thickness limits and proper installation will ensure reliable operation.
